BOURAOUI, Zied et al. Cytochemical responses of Hediste diversicolor (Nereidae, Polychaete) sampled from polluted sites along the Tunisian coast. RGCI [online]. 2014, vol.14, n.1, pp.119-127. ISSN 1646-8872.  https://doi.org/10.5894/rgci480.

The polychaete worm Hediste diversicolor was collected in several sites from the Tunisian coast. The aim of our study was to study several cytochemical biomarkers in this species in response to a pollution gradient caused by various discharges a long the Tunisian coast. Worms were collected from six sites: Bizerta Lagoon, Gargour, Nakta, Mahres, Skhira and from Teboulba, witch is considered a reference site. H. diversicolor. They are consistent with the chemical analysis and that worms from Bizerta and Mahres have been submitted to high levels of pollution.
